"Some of these families shared with us that, since the only time many of them see one another is at drop-off and pick-up times, we host some events where black families can meet one another, connect with one another and share their experiences about the school with one another. We are honoring their request."
"All families are welcome to attend all of our events, and families from a variety of backgrounds have done so."
The event was canceled due to COVID-19 restrictions, though the school declared it will continue in 2022.
